JTAG Applications

Where can JTAG be applied?While it is obvious that JTAG based testing can be used in the production phase of a product, new developments and applications of the IEEE-1149.1 standard have enabled the use of JTAG in many other product life cycle phases. Specifically, JTAG technology is now applied to product design, prototype debugging and field service as depicted in Figure 3. This means the cost of the JTAG tools can be amortized over the entire product life cycle, not just the production phase.
